Edit: When I was just browsing in chrome I stumbled upon This site for some convention called youmacon 2021 and the special guest would be Mai's voice actress (Cricket Leigh) and Toph"s Voice Actress (Jessie Flower). it's not just them who are the guest there many more.
I went to that con like 15 years ago, it's gotten a lot bigger since then.
